Memory is used to load detailed topographic maps, street-level maps, or additional waypoints into your GPS receiver. Detailed maps can use a great deal of memory on your device, so you need to consider how much internal storage capacity your device has. Higher end GPS devices also usually accept a memory card for additional storage. You can also share data easily between different GPS units of your own, or with a friend if you are using a memory card. There are several sizes of memory cards to choose from to expand the memory of your GPS navigation system. Most are between 1 and 4 GB of memory; although, you can purchase larger or smaller memory cards than this if you are interested, depending on how you plan use your GPS units.

What is a Basemap, and Do I Really Need One?

A basemap on your GPS navigation unit is highly recommended. It is a basic set of map data that comes included when your purchase your device. The increase in your unit’s usefulness is substantial, and the additional cost to you is marginal. A base map is built into your GPS device and cannot be removed. It is intended to be used for areas where you have not yet loaded detailed map data into your GPS unit’s memory. The specific information which is included in a basemap varies. Basemaps range from those including only major highways, towns and major landmarks, to large and detailed databases that are very useful and comprehensive right out of the box. The level of detail available in a typical base map shows highways, interstates and major roadways, but smaller local roads are not generally included in the typical base map.
Driving directions can be incredibly useful, so consider this feature in a higher end device. You may want to add to or update the basemap with additional free or purchased maps to make your GPS device truly useful. Basemaps may be updated and enhanced via purchased CDs, downloads from Web sites, or via purchased software and memory cards for GPS or additional cartography that have map and other data already in place.
